The special bag, created by Goodby Silverstein & Partners, comes equipped with a sensor connected to a microcontroller calibrated to detect small traces of alcohol on a person’s breath. If any alcohol is detected, the sensor turns red and forms the image of a steering wheel, along with an Uber code and a “Don’t drink and drive” message. 

The bag also uses near-field communication (NFC) technology, allowing fans to tap the bag with their phone to call a ride. With Uber and Mothers Against Drunk Driving, Tostitos will offer partygoers $10 off their Uber ride during and after the Feb. 5 game.
